3D Helicopter Cake, Lifted Off Cakeboard

My son wants this for his birthday and I always like a challenge but I'm going to need some help on this one. I make 3 cakes a year, one for each of my kids and thus not the most experienced so bring on the details and advice. I prefer to make it of all edible parts.

Just a guess but I would think the board the cake is setting on is supported by more then just fondant or gumpaste "landing gear", Screws or nails or pegs could be attached to the bottom of the board and then covered in fondant.

The landing gear would be dowels screwed to the board...you'd also probably need a dowel supporting the tail but you could cover those with "clouds" either gumpaste ones OR drape white satin or cotton around to look like clouds.

You'd have a board supporting the bulk of the cake and maybe icing or a tiny bit of RKT under the board to round out the underbody of the cake.
